2. Create a subscription and a database
3. In the database details, copy the Endpoint (host and port)
4. Copy the Default User Password

Troubleshooting

Connection Error

• Verify the host and port are correct
• Confirm the Redis server is running
• Check that the firewall allows connections to the Redis port

Authentication Error

• Verify the password is correct
• If Redis doesn’t require a password, leave the field empty

Connection Refused from Outside

• Redis by default only accepts local connections
• Configure bind in redis.conf to allow remote connections
• Use SSL/TLS for remote connections

---

Security

• Always configure a strong password for Redis
• Do not expose Redis directly to the Internet without protection
• Use SSL/TLS for remote connections
• Configure the bind parameter to restrict listening interfaces
• Disable dangerous commands with rename-command in the configuration
• Use private networks or VPN for inter-service communication
• Monitor active connections with the CLIENT LIST command
